.TH supernode 1  "Jan 3, 2009" "revision 3679" "USER COMMANDS"
.SH NAME
supernode \- n2n supernode daemon
.SH SYNOPSIS
.B supernode \-l <port> -c <community file path>[\-v]
.SH DESCRIPTION
N2N is a peer-to-peer VPN system. Supernode is a node introduction registry,
broadcast conduit and packet relay node for the n2n system. On startup supernode
begins listening on the specified UDP port for node registrations, and other
packets to route. The supernode can service any number of communities and routes
packets only between members of the same community. The supernode does not hold
the community encryption key and so cannot snoop or inject packets into the
community.
.PP
Supernode can service a number of n2n communities concurrently. Traffic does not
cross between communities.
.PP
All logging goes to stdout.
.SH OPTIONS
.TP
\-l <port>

\-c <community file path>
Load the list of allowed n2n communities from file. Default: all communities are allowed

.SH EXAMPLES
.TP
.B supernode -l 7654 -v
Start supernode listening on UDP port 7654 with verbose output.
.PP
.SH RESTART
When suprenode restarts it loses all registration information from associated
edge nodes. It can take up to five minutes for the edge nodes to re-register and
normal traffic flow to resume.
